I WILL MAKE WHOEVER ANSWERS THIS CORRECTLY THE BRAINLIEST :D Rei is barricading a door to stop a horde of zombies. She stacks boxes of books on a table in front of the door. Each box weighs 30 kilograms, and the table with 8 boxes on top weighs a total of 310 kilograms. The total weight W of the barricade in kilograms is a function of x, the number of boxes Rei stacks on the table. Write the function's formula.

Step-by-step explanation:

First, we will find the weight of the table. We know that 8 boxes weighs a total of 240 kg since each box weights 30 kg. Then to find the weight of the table, we can subtract the total weight from the weight of the boxes. Thus:

So, the weight of the table is 70 kg.

Now, we can write our function. Let equal the amount of boxes.

The table is a set weight, so that would be our constant.

Thus, we will have:

Where W(x) represents the weight of the table after adding x boxes.

30x represents the weight each box of book adds to the total. One box equals 30 kg, two boxes equal 60 kg, etc.

The 70 represents the unchanging weight of the table.
